Turns out that many of the things Huffington suggests line up
with a practice sleep scientists advocate using called "sleep
hygiene," a broader set of healthy behaviors designed to prepare
our bodies for a night of rest.

Here's how it works:

1. Have a sleep ritual

In her book and in interviews, Huffington has spoken about the
importance of carving out a period of transition between the
state of being wakeful and alert and being calm and ready for
sleep.

This practice is an important component of sleep hygiene because
it helps tell our bodies that we're getting ready for rest.

"When you're going to bed, you want to do things that are
relaxing, like reading a book," said Dasgupta. "You want to
gradually transition into sleep."

2. Clear away distractions

Huffington said she also removes all electronic devices —
tablets, phones, computers — from her bedroom so as to avoid
attention-grabbing things like email, the news, or social media.

This is another classic sleep hygiene approach. "At bedtime, you
want to be at peace," Dasgupta said. "Things that will probably
make you feel not at-peace include the news."

While Huffington writes that she turns off all her devices 30
minutes before bedtime, some experts suggest a slightly larger
device-free window of roughly an
hour before bed.

3. Bring the day to a close

If you struggle at night with feeling like you just didn't finish
everything on your to-do list, it might be helpful to do
something at bedtime that tells your brain and body that the day
is truly over.

Huffington says before getting into bed, she uses a journal to
jot down
three things she’s grateful for. Since it involves a classic
pen-and-paper approach, this would easily fall into both of the
categories above. And it also reflects the idea of positive
psychology, a theory that focusing on the good aspects of one's
day can help you feel
happier and more satisfied.
